 Thermal simulation of the human eyeball has been considered in recent years to investigate the effect of external heat sources as well as to predict ocular abnormalities and vital vision disorders. Due to the advances in the field of computing technologies, the use of computer simulation methods such as the use of simulation software and also the use of that software in areas such as medical sciences have received much attention, so that the results have been very helpful in diagnosing various eye diseases and inflammations in the medical community. In the present study, a two-dimensional finite element model has been used to simulate the transfer of biothermal heat in the human eye at steady state. In this study, COMSOL Multiphysics 4.4 software was used to simulate heat transfer in the human eye at steady state. The results of this modeling were compared by examining the effective parameters such as the effect of ambient temperature, blood temperature, lens conduction coefficient, blood transfer heat transfer coefficient, corneal surface diffusion coefficient and the effect of tear evaporation rate. Ocular inflammation is the strongest factor and also the impossibility of ignoring the amount of eye radiation with the environment and the effect of this factor on a significant increase or decrease in corneal surface temperature.
